-The ModScan application operates as a MODBUS mastermodbus_protocol device

in either RTU or ASCII transmission modes.　ModScan may be used to access

and modify data points contained in one or more MODBUS slave devices

connected to the PC via a serial port, modem, or network.　ModScan supports

the standard MODBUS message types 01-06, 15 & 16, as well as providing

the ability for you to exercise special features of a slave device by

transmitting custom command strings and observing the response.　ModScan

is a useful test and diagnostic tool for verifying the proper slave

response to MODBUS queries as well as being a low cost data collection

tool for interfacing data into PC　and spreadsheet applications.
